I know it sounds odd but popping seat is best way to describe my issue. I have standard seat with supple leather. Sometimes I feel a slight thump or pop on both driver and passenger side when you sit down or accerlerate /stop. This is most prevalent at the seat bottom and lumbar area. It's not too bad and I doubt that I will be able to duplicate it when I go to the dealer but has anyone else experience this?

I am not overweight so I doubt that's the issue

 

Yes, my driver seat does this if its not all the way on the floor, very annoying, but luckily Im not short and drive with the seat all the way down anyways. Ive also experienced it on an M coupe and 745i and Id venture a guess Recaro might be the manufacturer of all of the seats!

 

Thanks gmoney. I am not even sure if this is worth complaining to the dealer.

 

I think it would take away from the enjoyment of the car a lot, a good tech should feel it and fix, I would mention it.
